SPECIFICATION ,forming part of Letters Patent No. 240,755, dated` April 26, 1881.

Application tiled February 16, 1881. '(No model.)

` 'exact description ot'theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specicationft This invention relates to `certain improvement-s in valvular devices, such as globe-` valves, cocks, faucets, and check, pump, gate, and other valves for use in controlling steam, water, or gas.

The invention consists, first, in improvements in the seats for valves, whereby wearing away of the metallic seat is prevented by the jamming of an imperfect or worn disk- "holder, and space left for sediment, Ste., without interfering with the disk; and, second,in improved means for attaching the valve or disk holder to the stem on1 spindle.

In the accompanying drawings, illustrating my invention, in the several figures of which like parts are correspondingly designated, Figure lis a central vertical section of a globevalve embodying all of my aforesaid improvements. Fig. 2 is a side elevation of the divided box and locking device separated, and ot' the spindle and valve-holder. Fig. 3 is a top view of a globe-valve shell, showing the valveseat provided with two or more lugs to lprevent the wear oi' said seat by jamming down the valveand to obtain sediment-space. Fig. 4 isla perspectiveview of the disk-holder and a portion ofthe spindle, illustrating the mode ot' attaching or swiveling said holder to the spindle to permit of' itslfree movement and to prevent its accidental detachmentin the operation of the valve 5 and Fig. 5 shows two modiiications of this construction.

The divided automatic stufting or packing removing box a is screwed to the bonnet b, as usual in my inventions, (shown in my Patent No. 213,239, dated March l1, 1879, and in my application No. 17 ,5S8,) and may be locked the stem.

thereupon by an inside nut, c, or an outside nut, d, engaging with threads on the bonnet. tThe outside nut being more accessible, no necessity existing for disconnecting the box. asin the case of the inside nut, to operate it, I consider said outside nut to this extent the more preferable. t

Where the valve or disk holder containing composition disks is ground to obtain a new surface or tight lit, the less metal to be removed the more expeditious and economical the repairs. To this end I provide the teat, here designated e, (shown solid in my former application aforesairh) with a cavity, ff-that is to say, I make said teat partly tubular, so as to leave simply a narrow rim, instead of the Whole body of the teat, to be removed in refacing or grinding.

rlhe disk is herein designated g, and its holder h may be provided with thebeveled, roughened, or equivalentV disk-chamber', and said diskmay be inserted as described in my hereinbefore-rei'erred-to application. p

The valve-seat may be a beaded or raised rim, fi and to lprevent metallic contact of the holder h, as itsl disk wears away, with the web on which said seat ismade, Iand also obtain a space for the collection of sediment and grit without interfering with the valve, I provide a plurality of lugs,j, adjacent to said rim fi, t receive the holder as its disk is worn.

WVhen the disk-holders are swiveled to the valve stem or spindle, as heretofore, they are liable to accidental detachment from said stem or spindle by the operating of the valve. My invention is designed to, and does, et'fectually prevent this; and it consists in flanged lugs k rising from the disk or valve holder, which receive the shouldered or flanged end l of the spindle m to prevent longitudinal displacement, the two being connected and held from lateral displacement by a` pin, a, ttting in aligned sockets 0 p in the spindle and holder, respectively, this pin being secured from dropping out or displacement by a pin,or, better, a wire, r, passed through a transverse hole, s, in the stem, intersecting the pin-socket o therein. This wire is then secured by bending it around The pin n, of course, cannot pass the wire-s, and hence it is held down in the lic sockets, and while allowing perfectfreedom of motion,even swiveling, to the holder, this construction absolutely prevents the accidental displacementordetachingoftheholder. When the holder is to be removed the wires is taken out, the valve inverted, and the pin dropping down into the socket o, which is of greater length than the pin,and hence wholly contains it, then the holder is free to be slipped oft' the spindle. rlhe spindle and holder are connected by placing the pin Wholly within the stemsocket 0, running the flanged end of said stem into the flanged lugs ofthe holder until the pin drops into the holder-socket p, when the pin may be secured by the wire s or the plug t.

The valve-holder is more readily ground or refaced if it be connected to the spindle by a square or other than round pin and sockets or,

cavities,sucheonstruction preventingthe turning of the holder on its stem, but allowingl it perfect freedom ot' motion otherwise. (Sec the lower part ot' Fig. 5, where thisis indicated.)

ln Fig. 5 I have shown the piu n, in a socket the length oi' the spindle, and secured therein by a plug, t. This pin may be either round or square, or other shape than round, forthepurpose next above described.

What I claim isl. A valve-seat having a plurality of adjacent lugs,j, to receive the valve-holder as it wears, to prevent metallic contact of the valve and its seat, and provide a sediment-space, substantially as described.

2. A valve-holder having flanged lugs 7c and a stem provided with the shouldered end l, to engage said lugs to hold the holder against accidental longitudinal displacement, combined with a removable pin, n, fitted in said valveholder and spindle, and securely retained therein to prevent lateral displacement, substantially as described.

3. The socketed and flanged valve stem or spindle and the socketed and flanged valveholder, combined With a pin placed in the sockets in both and removably retained therein by a suitable locking device. substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
